I made a fixture to measure propeller pitch and shape using a SBC block stood on the front end, a cut off crankshaft with just rear and #4 mains, bored a 1" hole through the rear main for a stub of a prop shaft to fit, and a flywheel marked with 360 degrees, long studs in bell housing bolt holes to attach pointers, contour gauges and dial indicators, or used magnetic bases on the bell housing flange. It worked great. With guidance from some mid-50s NACA technical reports I learned a lot with it about supercavitating and regular propellers and gained a substantial advantage in controlling how the boat(s) rode by focusing and directing the thrust and increased speed from reduced friction and increased thrust.
